Sedimentary rock can be changed into igneous rock by undergoing melting and then solidification. At a subduction zone (at a convergent plate boundary, where one plate slides beneath another), layers of sedimentary rock will be assimilated into the mantle.edimentary rock to change to Igneous rock by applying heat and pressure, which creates Metamorphic rock. Next, Metamorphic rock turns to Magma because it melts. Lastly yo â¦ u have to let the Magma cool and it becomes an Igneous rock.
Organic sedimentary rocks are formed under varying degrees of pressure and temperature over long periods of time. More pressure and an increase in temperature will form different types of organic sedimentary rocks. When organic material is broken down it becomes peat. Peat is the first step in the organic sedimentary rock process. As more earth accumulates over the peat and causes the peat to come under greater pressure and a higher temperature, then lignite is formed, another type of organic sedimentary rock. After the lignite is formed it begins to undergo a similar process as the peat.
